  • a second pair of stopper bolts 52a and 52b are screwed into the lower half of the bracket 14 and extend obliquely downwardly relative to the vertical plane at an angle of 45°, respectively, on the opposite sides of the vertical plane.
  • a stopper lever 53 is pivotally mounted on a front surface of the middle portion of the support member 15 and includes, at its upper portion, a boss 53a which is rotatably supported by the support member 15 through a support pin 54.
  • the stopper lever 53 includes a stopper portion 53b positioned within the recess 50. The lower end of the stopper portion 53b can be selectively positioned for abutment on the upper end of one of the pair of the stopper bolts 51a and 51b through pivotal movelent of the stopper lever 53.
  • An extension 53c is integrally formed with the front portion of the stopper portion 53b for operation by the operator.

  • a stopper member 59 having substantially rectangular configuration in section is integrally formed with the boss portion 15a of the support member 15 and extends horizontally within the lower part thereof. The end portion of the stopper member 59 protrudes into the bracket 14 for abutment on either of the second pair of the stopper bolts 52a and 52b. The stopper member 59 is positioned on the vertical plane which passes through the central axis of the support bolt 17 and that of the support pin 54.
  • the support bolt 17 is loosened to some extent to permit lateral pivotal movement of the support member 15 relative to the bracket 14.
  • the miter saw unit 21 is moved together with the support member 15 to be inclined from the vertical position shown by a solid line to a rightward position shown by a chain line in FIG. 2 where the saw blade 36 is inclined at an angle of 45° relative to the vertical plane.
  • the stopper portion 53b is moved away from the left side stopper bolt 51a of the first pair and lies substantially horizontally while left side surface of the stopper member 59 abuts on the left side stopper bolt 52a of the second pair.
  • the motor housing 40 accommodating the motor 41 lies horizontally at a position above the turntable 3 and the fence 6 since the longitudinal axis of the motor housing 40 as well as that of the motor 41 and the motor shaft 42 obliquely extends relative to the saw blade 36 by the angle of 45°.
  • the support bolt 17 is thereafter tightened so as to fix the support member 15 to the bracket 14.
  • the motor 41 is started to rotate the spindle 38 together with the saw blade 36.
  • the bevel gear 39 which is in engagement with the gear 42a of the motor shaft 42 is rotated, so that the saw blade 36 is rotated with the spindle 38.
  • the operator thereafter pulls the miter saw unit 21 on his side, with the aid of the bearing cylinder 19a formed as the angular ball spline, so that the slide bar 18 is drawn toward the operator relative to the support member 15 in a rightward direction in FIG. 1.
  • the safety cover 48 is moved by the operational link 49 to uncover the exposed half of the saw blade 36 in response to movement of the miter saw unit 21. Consequently, the operation can be performed to cut a work which is placed on the turntable 3 and is fixed in postiion.
  • the movement of the slide bar 18 relative to the support member 15 is stopped through abutment of the stopper member 26 on the cover member 20. Further, the lowermost position of the miter saw unit 21 is determined by the stopper bolt 46 which abuts on the stopper member 47.
  • the motor housing 40 accommodating the motor 41, since the longitudinal axis of the motor housing 40 is inclined relative to the saw blade 36 by the angle of 45° as described above, the motor housing 40 lies horizontally above the turntable 3 and the fence 6 and is spaced therefrom, so that the motor housing 40 may not abut on the work to be cut.
  • the miter saw unit 21 When the operator releases the downward pressing force applied to the miter saw unit 21 after completion of the cutting operation, the miter saw unit 21 is returned to the uppermost position by the biasing force of the compression spring 45, and the safety cover 48 is also returned to cover the exposed half of the saw blade 36 in response to such a movement of the miter saw unit 21.
  • the operator moves the miter saw unit 21 to pivot in a reverse direction or the left side direction.
  • the stopper portion 53b of the stopper lever 53 again abuts on the stopper bolt 51a of the first pair, so that the miter saw can be operated to vertically cut the work.
  • the stopper member 59 of the support member 15 is moved away from the stopper bolt 52a of the second pair and is positioned at a middle position between the stopper bolts 52a and 52b.
  • the operator wishes to leftwardly incline the miter saw unit 21 from the vertical position, he moves the stopper lever 53 to the position for abutment on the stopper bolt 51b of the first pair as shown in FIG. 8. The operator thereafter loosens the support bolt 17 to permit movement of the support member 15 relative to the bracket 14. Then, the operator moves the miter saw unit 21 to pivot the support member 15 relative to the bracket 14 in a leftward direction in FIG. 2.
  • the stopper portion 53b of the stopper lever 53 is moved away from the right side stopper bolt 51b of the first pair and lies substantially horizontally, while the right side of the stopper member 59 of the support member 15 abuts on the right side stopper bolt 52b of the second pair as shown in FIG. 9.
  • the longitudinal axis of the motor housing 41 as well as that of the motor 40 extends vertically and the motor housing 41 is kept to be spaced from the turntable 3 and the fence 6.
  • the support bolt 17 is again tightened to fix the support member to the bracket 14, so that the oblique cutting operation on the opposite side can be performed.
  • an inked line drawn on the work can be easily recognized by the operator, so that the cutting operation can be reliably performed.
  • the operator pivots the miter saw unit 21 in a reverse direction.
  • the stopper portion 53b of the stopper lever 53 abuts on the left side stopper bolt 51 of the first pair, so that the vertical cutting operation can be again performed.
  • the stopper member 59 of the support member 15 is moved away from the right side stopper bolt 52b of the second pair and is positioned at the middle position between the stopper bolts 52a and 52b as shown in FIG. 8.
  • the position of the stopper portion 53b of the stopper lever 53 is kept at either the positions for abutment on the first pair of the stopper bolts 51a and 51b through engagement of the engaging ball 56 with the corresponding engaging recess 58a or 58b.
  • the miter saw 1 of the above embodiment can be used for the oblique cutting operation by laterally inclining the miter saw unit 21 in either of leftward and rightward directions, and therefore, the oblique cutting operation for both opposite sides can be easily performed for a work having a deformed profile in section as well as a work having a longer length.
  • the operation for fixing the support member 15 to the bracket 14 and for releasing the same can be performed at a position on the pivotal axis of the support member 15 through the support bolt 17 and the nut 17a. Therefore, the construction becomes simple and the fixing operation can be reliably performed without causing unstable support of the support member 15.
  • cutting chips or dust may not enter the pivotal support portion of the support member 15, and the cutting chips or the dust may be stained to the stopper member 59 or the second pair of the stopper bolts 52a and 52b for abutment on the stopper member 59 since they are disposed within the support shaft 16 of the bracket 14.
